Reaction Steps

Dissolve anhydrous cobalt(II) acetate (700 mg, 4 mmol ) in dimethylformamide (150 mL). Add 2,2'-dipyridyl (600 mg, 4 mmol) and stir for 30 minutes. Add 4-pyridinecarboxaldehyde (5 g, 50 mmol) and 2-acetylfuran (5.5 g, 50 mmol). Heat at 80° C. for 18 hours. Evaporate the solvent and purify the residue by silica gel chromatography (1:1 toluene/ethyl acetate) to yield 30 mg of the title compound; mp 122°-124° C.
